Operation REDWING, a 17-test nuclear weapons series, was conducted at the Pacific Proving Ground between May 4 and July 21, 1956. The Atomic Energy Commission (AEC) tested high-yield thermonuclear devices that could not be tested at the Nevada Test Site.

Over 10,000 military personnel and civilian employees of the AEC and the Department of Defense participated in these nuclear tests. The LACROSSE and CHEROKEE tests were observed from aboard the USS Mount McKinley by 15 American press, radio and television reporters. These were the first uncleared U.S. civilians in ten years to observe an American nuclear test in the Pacific.

The AEC's progress in miniaturization of warheads had accelerated to where the equivalent of the nearly 90-ton weight of the MIKE device in Operation IVY could now be dropped from a bomber. Operation REDWING also further advanced the AEC's designs of nuclear weapons that would produce reduced fallout and provided new information for the design of nuclear warheads for missiles.

Complete weapons systems were exposed to blast effects in Operation REDWING, and a fallout computer was successfully used for the first time. The series included the CHEROKEE test, the first airdrop by U.S. of a thermonuclear weapon.

This formerly secret film was produced through the top secret Lookout Mountain Laboratory, located in the Hollywood Hills of California, under the joint command of the United States Air Force and the Armed Forces Special Weapons Project (AFSWP).

The intention of this film was a derivative technical report for viewing by top secret oversight committees of United States Congress and as a project film archive of the United States military.
